Method and System for Measuring a Perpendicular Wind Component

摘要

The present invention concerns a method for measuring a perpendicular wind speed component with respect to a suspended cable span (2), comprising the steps of monitoring a motion of at least one point of said suspended cable span (2) over a time interval, and determining whether said motion comprises an Aeolian vibration. If said motion is not determined to comprise an Aeolian vibration, a transverse swing angle of the suspended cable span (2) is measured and said perpendicular wind speed component is calculated as a function of said transverse swing angle, whereas if said motion is determined to comprise an Aeolian vibration, a frequency of said Aeolian vibration is measured and said perpendicular wind speed component is calculated as a function of said Aeolian vibration frequency. The present invention also relates to methods for measuring an effective incident radiation and for determining a maximum allowable current rating, or “ampacity”, for the suspended cable span, as well as for supplying electric power over a power line comprising said power span. It also relates to systems for implementing any one of these methods.
